To solve this problem, you need to set up a proportion. If she jogs 6 miles per hour, then this can be written as . If there are 5280 feet in a single mile, then first we multiply the two proportions like this:
The two 'mile' values cancel each other out, so then just multiply . This equals to 31680 feet per hour. Now let's convert to seconds.
, or 360 seconds every hour. Since hours are much longer than seconds, multiply 31680 by the reciprocal of 360, so that it makes sense.
She runs 88 feet per second.
Answer:
1. y = -11/4; (-2, -11/4)
2. y = -1; (0, -1)
3. y = -1/8; (1, -1/8)
4. y = 0; (8/7, 0)
5. y = 3/4; (2, 3/4)

Step-by-step explanation:
x+y=8
28x+12y=144
-12x-12y=-96
16x=48
x=3
